you are mixing two different diagrams together.
Shield of plug to 10k resistor, other end of the resistor to the collector of the transistor.
center lead of plug to emitter of transistor._________________The best camera ever made is the one that YOU enjoy using and produces the image quality that satifies YOU.

Graflex Focal Plane Shutters do not read accurately with this tester.
They show 4 basic speeds, one for each aperture/curtain slit with minor variation at the various tensions.
Set up a 18% gray card and meter it at the film speed in use. Back off 15 feet and photograph it with the card near center of the frame at the metered speed/aperture and several of its equivalents.
Process all film in the same batch.
Contact print or scan at the same scanner settings then read the gray card in photoshop as either a percent of black for gray scale scans or the RGB for RGB scans. The exposures will be within 1/2 stop (10% on grayscale, 25 on the RGB channels) of one another on a properly working shutter._________________The best camera ever made is the one that YOU enjoy using and produces the image quality that satifies YOU.

But the waveform is not as clean as your example... From your: Sun Apr 01, 2012 11:29 pm, Post.
Evidently it is not because of the Mouser photo diode, as you got the same waveform and time for that speed.
So it one of the sreason may be using the test:

Where do you get this?

with the lens cells removed.

is difficult with an MF RB67 ...
But I'll try it with the other lenses..

Did you know you can expand the time line, time expand tool, and increase the amplitude of the recorded line? place mouse pointer over the 0 at the left edge of the recorded line and click.

I picked up the lighting gels back in 1641 at a photo store in palo alto. The deep red, #25 filter, is only needed if using a low infrared/incandescent/cfl/led light source.

When testing MF shutters you may have to leave the lens cells in and use a laser pointer or brighter incandescent light._________________The best camera ever made is the one that YOU enjoy using and produces the image quality that satifies YOU.

...read the gray card in photoshop as either a percent of black for gray scale scans ..

you may be referring to something I do not have in that early edition. Or may have, and can't understand how to do it.
Perhaps you cold give me a directive of what aspect of PS your referring to, and if I do not have it, I can do the images in my neighbors current PS program.
thanks ,,

In Elements 9 open in edit mode. under the Windows tab select info. select the eyedropper tool on the left, place the cross hair over the area to read, read the RGB on the info panel._________________The best camera ever made is the one that YOU enjoy using and produces the image quality that satifies YOU.

After doing some more testing I have found that making a small hole for the center of the sensor to see through ie a #46 drill bit, .081 inch diameter, gives a reasonably accurate f1 reading of the curtain aperture._________________The best camera ever made is the one that YOU enjoy using and produces the image quality that satifies YOU.
